Description

Bei Lokomotiven mit Kolbenschiebern, insbesondere Heiß dampf lokomotiven, werden die Zylinderseiten beim Leerlauf durch Druckausgleichvorrichtungen, die meist mit Druckluft betätigt werden, miteinander verbunden. Ferner gibt es Anordnungen für den Druckausgleich, die beide Zylinderseiten direkt über die Ausströmkanäle und die Rauchkammer verbinden. Durch diese Anordnung werden Rauchgase angesaugt, durch dieFor locomotives with piston valves, in particular Hot steam locomotives, the cylinder sides when idling by pressure equalization devices, which are mostly operated with compressed air, connected to each other. There are also arrangements for pressure equalization, both of which Connect the cylinder sides directly via the exhaust ducts and the smoke chamber. Through this arrangement fumes are sucked in through which

ίο Zylinder gedruckt und diese dadurch verunreinigt und abgeschliffen. Die Erfindung betrifft einen Druckausgleichkolbenschieber mit innerer Einströmung für doppelt wirkende Kolbendampfmaschinen mit wenigstens zwei Gruppen von Kolbenringen, die jeweils nahe den steuernden Schieberkanten angeordnet sind, mit Schieberkörpern, die aus je zwei Einzelkörpern bestehen, von denen der eine mit der Schieberstange fest verbunden ist, während der andere bewegliche Einzelkörper in der Arbeitslage des Kolbenschiebers unter Einwirkung einer zwischen den beiden Einzelkörpern angeordneten Feder vom festen Einzelkörper abhebbar ist, vorzugsweise für Lokomotiven. Die Erfindung bezweckt, den Druck-ίο cylinder printed and thus contaminated and sanded off. The invention relates to a pressure compensation piston valve with internal inflow for double-acting piston steam engines with at least two groups of piston rings, each close to the controlling one Slide edges are arranged with slide bodies, each consisting of two individual bodies, one of which is firmly connected to the slide rod, while the other is movable Individual body in the working position of the piston valve under the action of a between the two individual bodies arranged spring can be lifted from the solid individual body, preferably for Locomotives. The purpose of the invention is to

It can with

dieser Wegführung keine zerstörenden Teile, wie Lösche und Schlacken, in die Zylinder gelangen, es wird eine unnötige Abnutzung der gleitenden Teile im Zylinder und im Schieber vermieden.this route no destructive parts, such as sludge and slag, get into the cylinder, it unnecessary wear of the sliding parts in the cylinder and in the slide is avoided.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar in einem Längsschnitt.In the drawing, the subject matter of the invention is shown, for example, in one Longitudinal section.

Die ringförmigen Schieberkörper bestehen aus je zwei Einzelkörpern E und F, die nahe den steuernden Kanten C und D jeweils Gruppen von Kolbenringen A und B tragen. Bei Dampfeintritt werden die beiden Körper fest aufeinandergepreßt und damit der Schieber geschlossen, wie dies in der Zeichnung oberhalb der Mittellinie dargestellt ist. Hierbei wirkt der Dampfdruck auf den Ringraum, der von der Außenfläche des inneren Kolbenschieberteils und der Dichtungsfläche zwischen beiden Schieberteilen gebildet wird. Bei Fortnahme des Dampfes, also beim Leerlauf, werden die Körper E und F durch eine dazwischenliegende Feder G auseinanderbewegt und damit der Schieber geöffnet, wie in der Zeichnung unterhalb der Mittellinie gezeigt. Der Druckausgleich kann nun über die Einströmkanäle H und / und durch die Durchbrüche K der innenliegenden Körper F ungehindert erfolgen. . ■The ring-shaped slide bodies each consist of two individual bodies E and F, which each carry groups of piston rings A and B near the controlling edges C and D. When steam enters the two bodies are pressed tightly against one another and thus the slide is closed, as shown in the drawing above the center line. The steam pressure acts on the annular space, which is formed by the outer surface of the inner piston slide part and the sealing surface between the two slide parts. When the steam is removed, i.e. when idling, the bodies E and F are moved apart by an intermediate spring G and the slide is opened, as shown in the drawing below the center line. The pressure equalization can now take place unhindered via the inflow channels H and / and through the openings K in the internal body F. . ■

In der Konstruktion ist darauf geachtet worden, daß die dem Frischdampf ausgesetzte Ringfläche so groß gewählt wurde, daß auch bei starker Drosselung die Körper mit Sicherheit aufeinandergepreßt werden. Die Feder G ist so stark bemessen, daß sie den Schieberkörper selbst bei schnellster Fahrt trotz der auftretenden Kräfte der hin und her gehenden Massen bei der Leerfahrt auf dem Totpunkt festhält und nicht schlagen läßt. Die Schmierung erfolgt in bekannter Weise wie bei der Regelbauart durch Schmierstutzen. Die Gleitflächen besitzen reichlich Spiel mit Labyrinthdichtung und federnde Kolbenringe.In the design, care has been taken to ensure that the ring area exposed to the live steam is chosen so large that the bodies are reliably pressed against one another even with strong throttling. The spring G is dimensioned so strong that it holds the slide body firmly at the dead point and does not let it hit, even during the fastest travel, despite the forces of the masses moving back and forth during the empty travel. The lubrication takes place in the known manner, as with the standard design, through lubrication nozzles. The sliding surfaces have plenty of play with the labyrinth seal and resilient piston rings.
